DOOR-OPERATING MECHANISM.

Specication of Iietters Patent.

Patented May 7, 13918.

Application filed June 27, 1917. Serial No. 177,308.

To all whom t may concern:

Be it known that l., Louis MEYER, a citizen of the United States, residing `at Milford, in the county of Iroquois and State of Illinois, have invented a new anduseful Door-Operating Mechanism, of which the following is a specification.

It isV the object of this invention to provide novel `means for swinging a door to and from an open position from a distant point, and to provide novel means for holding the door in an open or a closed position.

lVith theabove and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in front elevation, a dooroperating mechanism embodying the present invention;

Fig. 2 is a top plan of the structure shown in Fig. 1, parts being omitted;

Fig. 3 is a vertical section of the structure shown in Fig. 1, one of the doors being swung into a position at right angles to the wall of the building;

Fig. 4 is a fragmental elevation showing a part of the door-operating mechanism.

The numeral 1 indicates a support, such as the wall of a building. The support 1 has a doorway 2. The doorway 2 is controlled by a first door y3 hinged at 4 to the wall 1, and by a second door 5 hinged at 6 to the wall 1.

Mounted on the wall 1 above the doorway 2 is a horizontal U-shaped strip 7. A vertislanting strip or brace 8 is secured at the support 1.' The outer, lower end of the strip 8 terminates arm 9 attached by a securing element 10 to the bend of the horizontal U- shaped strip 7. The strip 8 includes a horizontal part 11, the arm 9 having a horizontal linger 12.

J ournaled in the members 11 and 12 is a vertical shaft 14 provided at its lower end with a fork 15. A nut 75 or the like on the upper end of the shaft 14, prevents the shaft 14 from sliding downwardly.

kedge of the door.

The numeral 16 denotes a vertically swinging main link. The outer end of the main link 16 is pivoted at 17 in the fork 15 of the shaft 14. rule joint 18 connects the inner end of the main link 16 with the outer end of an auxiliary link 19. The inner end of the auxiliary link 19 has a fork 20. The pivot element 21 is mounted in the fork 20. The pivot element 21 passes through a head 22 disposed in the fork 20, the head being mounted onk the upper end of a vertical shaft 23 journaled in bearings 24 and 25 on the outer face of the second door 5. rIhe shaft 23 has a collar 26, which, coacting with the bearing 24, holds the shaft 23 in the bearings 24 and 25 against downward movement. A helical spring 27 is coiled around one end of the pivot element 21. One end of the helical spring 27 is fashioned into an arm 28 engaged as indicated at 29 across the upper edge of the auxiliary link 19. The other end of the helical spring 27 is extended to form an arm 30 engaged as shown at 31 across the rear edge of the shaft 23, below the bearing 24.

A hanger 32 is mounted on the wall 1. The inner end of a bar 33 is pivoted at 34 to the hanger 32, for horizontal swinging movement. The rear edge of the bar 33 is provided with concaved seats 35 and 36, defining an apex 37 therebetween. The outer end of the bar 33 is connected by means of a retractile spring 38 with the wall 1. Near to its hinged edge, the second door 5 has a standard 39 which projects above the upper Mounted to rotate on the upper end of the standard 39 is a grooved wheel 40 engaging the rear or inner edge of the bar 33.

A flexible element 41 is connected as shown at 76 with the main link 16. The flexible element 41 is rove across a sheave 42 fixed to and depending from the strip 8. From the sheave 42, the flexible element 41 is extended across a pulley 43 carried by the support 1 adjacent the hinged edge of the door 3. From the pulley 43, the iiexible element 41 is extended downwardly through a guide 44 on the wall 1, the iiexible element being thence extended, as shown at 45, Fig. 3, rearwardly, across a pulley 46 carried by a post 47. The post 47 may be located at any desired distance from the building of which the wall 1 constitutes a part. A branch line 48 is connected with the iexible 19 into the element 41 below the pulley 43. The branch line 48 is extended through the guide 44; and thence is prolonged forwardly, as shown at 49, in front of the wall 1, around a pulley 50 carried byka post 51 which is located at any desired distance in front of the building of which the wall 1 constitutes a part.

As a preliminary statement, it may be set forth that the flexible element 41 may be manipulated either from in front of the building, by pulling on the end 49 of the flexible element, or it may be actuated at a point remote from the building, by pulling on the end l5 of the flexible element.

llVhen the door 5 is closed, the links 16 and 19 are in axial alinement and are horizontally disposed, and since these links are connected by the rule joint 18, the door 5 will be held in a. closed position. `When the flexible element -11 is drawn upon, the saine rides over the sheave l2 and causes the links 16 and 19 to knuckle upwardly into the position of Fig. 8. During this operation, the spring Q7 is pnt under tension, because its arms. 28 and 30 are engaged, respectively, with the link 19 and with the shaft 23. llVhen the door 5 is swung toward an open position, the wheel Ll() rides out of the seat 35, and by the time that the door 5 stands at right angles to the wall, the wheel is on the apex 37. This operation swings the bar 33 away from the wall 1, and the spring 88 is put under tension. The inertia of the door 5 moves the door toward an open position, beyond a position at right angles to the wall 1. The wheel 40 then rides into the seat 36, and the spring 38 reacting on the bar 83, swings the door 5 into a completel open position, it being recalled `that the wheel -lO is mounted on the standard 39 which is connected with the door 5. The links 16 and 19 now knuckle downwardly into axial alinement, thus holding the door 5 in a fully open position. The spring 27 and its arms Q8 and 30 aid in swinging the links 16 and 19 into alinement as aforesaid. lit will be understood that while the door 5 is swinging from a closed position to an open position, the shaft 14s rotates in the parts 11 and 12 of the strip 8, the shaft 23 rotating in the bearings 24 and 25 on the door 5.

l/Vhen it desiree to close the door 5, the process above described is reversed, the flexible element al1 knuckling up the links 16 and position of Fig. 3, and the door 5 finally swinging into a closed position, whereupon the links 16 and 19 will knuckle downwardly into alinement, the door 5 being held in a closed position, since the links 16 and 19 are connected by the rule joint union 18.

In order that the door 2 may be controlled by the movement ,of the door 5, a rod ma be pivoted at 8l to the rear face of the door 5, the rod 80 being pivoted as shown at 82 to an offset bracket 83 on the door 2. When the door 5 sta-nds in a fully open position, that is, when the door 5 is swung around `until it is'approximately parallel with the wall 1, the door 3 stands approximately at right angles to the wall 1. It will be obvious to those skillechin the art that the device forming the subject matter of this application will work either in` connection with one door or in connection withtwo doors.

lVhat is claimed is 1. In a device of the class described, a support; a door hinged to the support; a frame outstanding from the support; a shaft journaled in the support; a shaft journaled on the door and disposed parallel to the shaft in the frame; links having their outer ends hinged to the respective shafts for swinging movement in a plane defined by the axes of the shafts; a rule joint connecting the inner ends of the links; means for manipulating the links from a distant point; a bar hinged at one end to the support; yieldable means for moving the other end of the vbar inwardly with respect to the support, said yieldable means being effective to aid in swinging the inner ends of the links downwardly and to aid in closing the rule joint when the door is closed and when the door is fully opened; and a projection on the door, the projection being slidably engaged with the inner edge ofthe bar.
